This 1965 Fastback Mustang has been in the same family for 44 years. Currently the Fastback is powered by a turbocharged 1992 5.0 stroked to 349 cubes. Due to clutch issues the boost has been left at a conservative level producing an estimated 490 horsepower at the flywheel. The owner hopes to reach 560-580 horsepower in the future.
